Description

Technical Field

[0001] This utility model relates to an electronic device and housing assembly, and more particularly to an electronic device and housing assembly including a fan housing. Background Technology

[0002] Generally, fans are installed in the casing of electronic devices, such as those in laptops, to effectively dissipate heat generated by heat sources. After prolonged use, dust tends to accumulate in the fan or casing, thus affecting the fan's cooling efficiency.

[0003] However, traditional electronic devices lack built-in dust removal mechanisms. Therefore, users cannot clean these devices themselves and must instead return them to the manufacturer for cleaning. This increases the cost of cleaning electronic devices. Utility Model Content

[0004] The purpose of this invention is to provide an electronic device and housing assembly to reduce the cost of dust removal for electronic devices and housing assemblies.

[0005] An embodiment of this utility model discloses an electronic device comprising a housing, a motherboard, a fan assembly, and a channel switching component. The housing has an external air inlet, an external dust removal outlet, and a ventilation outlet. The motherboard is disposed within the housing. The fan assembly is electrically connected to the motherboard and includes a fan housing and a fan blade. The fan housing has an internal air inlet, an internal dust removal outlet, and an internal air outlet. The internal air inlet communicates with the external air inlet. The fan blade is rotatably disposed on the fan housing. The channel switching component includes a shielding member. The shielding member is movably disposed within the housing and includes a heat dissipation position and a dust removal position. A heat dissipation channel and a dust removal channel are defined. The heat dissipation channel passes through the external air inlet, the internal air inlet, the internal air outlet, and the ventilation outlet. The dust removal channel passes through the external dust removal outlet, the internal dust removal outlet, and the ventilation outlet. When the shielding member is in the heat dissipation position, the shielding member closes the dust removal channel and opens the heat dissipation channel, and the fan blade guides a cooling airflow through the heat dissipation channel. When the shielding component is in the dust removal position, it closes the heat dissipation channel and opens the dust removal channel.

[0006] According to one embodiment of the present invention, the external air inlet and the external dust removal outlet are located on the same side of the housing, the external air inlet and the ventilation outlet are located on opposite sides of the housing, the internal air inlet and the internal dust removal outlet are located on the same side of the fan housing, and the internal air inlet and the internal air outlet are located on opposite sides of the fan housing.

[0007] According to one embodiment of the present invention, the channel switching assembly further includes a linkage and a pivot. The shielding member is connected to the pivot member through the linkage. The shielding member includes a shielding plate portion, a connecting plate portion, and a first pivot portion. The opposite sides of the connecting plate portion are respectively connected to the shielding plate portion and the first pivot portion. The shielding plate portion has a groove. The housing has two pivot posts, which are rotatably disposed in the groove. The first pivot portion is rotatably disposed on the linkage. The shielding plate portion is used to close or open the heat dissipation channel and the dust removal channel.

[0008] According to one embodiment of the present invention, the linkage includes two assembly portions, a protruding plate portion, and two second pivot portions. The protruding plate portion connects to the two assembly portions and protrudes radially from the two assembly portions. The two second pivot portions are respectively located on the side of the two assembly portions away from the protruding plate portion. Each of the two assembly portions has a first pivot hole. The first pivot portion of the shielding member is rotatably disposed in the two first pivot holes, and the two second pivot portions are rotatably disposed in the pivoting member. The protruding plate portion is used to abut against the fan housing when the shielding member is in the heat dissipation position or the dust removal position.

[0009] According to one embodiment of the present invention, the pivot member includes a mounting plate portion and a third pivot portion. The third pivot portion is connected to one side of the mounting plate portion and is rotatably disposed on the housing. The mounting plate portion has a second pivot hole, and the second pivot portion of the linkage member is rotatably disposed on the second pivot hole.

[0010] According to one embodiment of the present invention, the channel switching assembly further includes at least one torsion spring, the opposite ends of which are respectively fixed to the housing and the third pivot portion of the pivot member, and the at least one torsion spring is used to prevent the shielding member from moving from the dust removal position to the heat dissipation position.

[0011] According to one embodiment of the present invention, a magnet is also included. The magnet is disposed in the housing. When the shielding member is located at the heat dissipation position, the magnet attracts the shielding member to position the shielding member at the heat dissipation position.

[0012] According to one embodiment of the present invention, the shielding member further includes a magnetic plate portion, the magnetic plate portion being disposed of the shielding plate portion, and when the shielding member is located at the heat dissipation position, the magnet attracts the magnetic plate portion.

[0013] According to one embodiment of the present invention, a radiator is further included, which is disposed in the housing and located in the heat dissipation channel and the dust removal channel.

[0014] Another embodiment of this utility model discloses a housing assembly comprising a casing, a fan casing, and a channel switching assembly. The casing has an external air inlet, an external dust removal outlet, and a ventilation outlet. The fan casing has an internal air inlet, an internal dust removal outlet, and an internal air outlet. The internal air inlet communicates with the external air inlet. The channel switching assembly includes a shielding member. The shielding member is movably disposed in the casing and includes a heat dissipation position and a dust removal position. A heat dissipation channel and a dust removal channel are defined. The heat dissipation channel passes through the external air inlet, the internal air inlet, the internal air outlet, and the ventilation outlet. The dust removal channel passes through the external dust removal outlet, the internal dust removal outlet, and the ventilation outlet. When the shielding member is in the heat dissipation position, the shielding member closes the dust removal channel and opens the heat dissipation channel, and the fan blades are used to guide a heat dissipation airflow through the heat dissipation channel. When the shielding member is in the dust removal position, the shielding member closes the heat dissipation channel and opens the dust removal channel.

[0015] According to the electronic device and housing assembly disclosed in the above embodiments, since the shielding member is movably disposed on the housing and includes a heat dissipation position and a dust removal position, and can selectively close or open the dust removal channel and the heat dissipation channel, the user can clean the electronic device and housing assembly by moving the shielding member between the heat dissipation position and the dust removal position. In this way, the cost of cleaning the electronic device and housing assembly is reduced.

[0016] Furthermore, since the shielding component closes the heat dissipation channel when it is in the dust removal position, the dust removal airflow through the dust removal channel will not flow to the fan blades when dust is removed from the electronic devices and housing components. In this way, the dust removal airflow will not damage the fan blades or allow dust to flow back into the fan housing. Attached Figure Description

[0062] Please see Figure 1 and Figure 2 . Figure 1 This is a partially enlarged perspective view of an electronic device according to an embodiment of the present invention. Figure 2 To present Figure 1 A partially enlarged side sectional view of the shielding component of the electronic device located at the heat dissipation position.

[0063] In this embodiment, for example, the electronic device 10 is the main body of a laptop computer and includes a casing 100, a motherboard 200, a fan device 300, a heat sink 400, a magnet 450 and a channel switching component 500.

[0064] In this embodiment, the housing 100 has multiple external air inlets 101, an external dust removal port 102, and a ventilation port 103. The external air inlets 101 and the external dust removal port 102 are, for example, located on the same side of the housing 100. The external air inlets 101 and the ventilation port 103 are, for example, located on opposite sides of the housing 100, such as adjacent sides. The main board 200 is disposed within the housing 100.

[0065] The fan assembly 300 is electrically connected to the motherboard 200 and includes a fan housing 310 and a fan blade 320. The motherboard 200 is electrically connected, for example, to a drive element (not shown) in the fan assembly 300 for driving the fan blade 320, such as a motor. The fan housing 310 has an internal air inlet 311, an internal dust removal port 312, and an internal air outlet 313. The internal air inlet 311 communicates with the external air inlet 101. The internal air inlet 311 and the internal dust removal port 312 are, for example, located on the same side of the fan housing 310. The internal air inlet 311 and the internal air outlet 313 are, for example, located on opposite sides of the fan housing 310, such as adjacent sides. The fan blade 320 is rotatably disposed on the fan housing 310.

[0066] Define a heat dissipation channel 150 and a dust removal channel 160. The heat dissipation channel 150 is connected to an external air inlet 101, an internal air inlet 311, an internal air outlet 313, and a ventilation opening 103. The dust removal channel 160 is connected to an external dust removal opening 102, an internal dust removal opening 312, and a ventilation opening 103.

[0067] A heat sink 400 is disposed within the housing 100 and located within the heat dissipation channel 150 and the dust removal channel 160. The heat sink 400 is, for example, a heat dissipation fin assembly. A magnet 450 is disposed within the housing 100.

[0068] Please see Figures 2 to 5 . Figure 3 To present Figure 1 A three-dimensional cross-sectional view of the assembly between the channel switching components and the housing of the electronic device. Figure 4 for Figure 3 3D exploded view of the channel switching component and the housing. Figure 5 for Figure 3 The channel switching components and the housing are shown in a three-dimensional exploded view from another perspective.

[0069] In this embodiment, the channel switching component 500 includes a shielding member 510, a linkage member 530, a pivot member 550, and two torsion springs 560. The shielding member 510 is connected to the pivot member 550 via the linkage member 530.

[0070] In detail, the shielding member 510 includes a shielding plate portion 511, a connecting plate portion 512, and a first pivot portion 513. The opposite sides of the connecting plate portion 512 are respectively connected to the shielding plate portion 511 and the first pivot portion 513. The shielding plate portion 511 has a groove 514. The housing 100 has two pivot posts 104. The two pivot posts 104 are rotatably disposed in the groove 514. The shielding plate portion 511 is used to close or open the heat dissipation channel 150 and the dust removal channel 160. In this embodiment, the shielding member 510 may further include a magnetic plate portion 515. The magnetic plate portion 515 is made of a magnetic material, such as metal, that can be attracted by a magnet 450. The magnetic plate portion 515 is disposed on the shielding plate portion 511. Therefore, the magnetic plate portion 515 can be used for attraction by the magnet 450, so that the shielding plate portion 511, the connecting plate portion 512, and the first pivot portion 513 can be made of lighter or cheaper materials such as plastic, but the present invention is not limited thereto. In other embodiments, the shielding member can also be made of magnetic materials such as metal that can be attracted by magnets, and can be attracted by magnets without including the magnetic plate portion.

[0071] The linkage 530 includes two assembly portions 531, a protruding plate portion 532, and two second pivot portions 533. The protruding plate portion 532 connects to the two assembly portions 531 and protrudes radially from them. The two second pivot portions 533 are respectively located on the side of the two assembly portions 531 away from the protruding plate portion 532. Each of the two assembly portions 531 has a first pivot hole 534. The first pivot portion 513 of the shielding member 510 is rotatably disposed in the two first pivot holes 534. The protruding plate portion 532 is used to abut against the fan housing 310 when the shielding member 510 is in the heat dissipation position or the dust removal position. In addition, the linkage 530 can be designed according to the shape of the fan blade 320, thereby adjusting the position of the channel switching assembly 500 according to the location of dust concentration.

[0072] The pivot member 550 includes a mounting plate portion 551 and a third pivot portion 552. The third pivot portion 552 is connected to one side of the mounting plate portion 551 and is rotatably disposed on the housing 100. The mounting plate portion 551 has a second pivot hole 553. The two second pivot portions 533 of the linkage member 530 are rotatably disposed in the second pivot holes 553. The opposite ends of the torsion spring 560 are respectively fixed to the housing 100 and the third pivot portion 552 of the pivot member 550.

[0073] By employing a three-piece design (i.e., shielding member 510, linkage member 530, and pivot member 550), the channel switching assembly 500 can be applied to fan units 300 or housings 100 of different sizes by modifying the dimensions (e.g., length) of at least one of the shielding member 510, linkage member 530, and pivot member 550. In other words, through the three-piece design, the channel switching assembly 500 can be used with different types of fan units 300 or housings 100, thus eliminating the manufacturing costs associated with developing dedicated components for different types of fan units 300 or housings 100.

[0074] It should be noted that in this embodiment or other embodiments, the housing 100, the fan housing 310 and the channel switching assembly 500 can be collectively referred to as the housing assembly.

[0075] Please see Figure 2 and Figure 6 In this embodiment, the channel switching component 500 includes a heat dissipation location (e.g., Figure 2 (as shown) and a dust removal location (such as) Figure 6 (As shown). Figure 6 To present Figure 1 A partially enlarged side sectional view of the shielding component of the electronic device located at the dust removal position.

[0076] First, such as Figure 2 As shown, when the shielding member 510 is in the heat dissipation position, it closes the dust removal channel 160 and opens the heat dissipation channel 150, and the fan blades 320 guide a heat dissipation airflow F1 through the heat dissipation channel 150. At this time, the vent 103 serves as the air outlet. Furthermore, the protruding plate portion 532 abuts against the fan housing 310 to prevent the shielding member 510 from rotating in a rotation direction R1. Additionally, the magnet 450 attracts the magnetic plate portion 515, and the attraction force generated by the magnet 450 on the magnetic plate portion 515 is greater than the torque of the torsion spring 560, causing the magnet 450 to position the shielding member 510 in the heat dissipation position. In other embodiments, the electronic device may also be free of magnets and instead use springs or hook structures to position the shielding member in the heat dissipation position.

[0077] Furthermore, in this embodiment, when the shielding member 510 is in the heat dissipation position, the shielding member 510 and the housing 100 together present a flat appearance.

[0078] like Figure 2 and Figure 6As shown, when the shielding member 510 is moved in a rotation direction R2 opposite to the rotation direction R1, the attraction force generated by the magnet 450 on the magnetic plate portion 515 is overcome, causing the shielding member 510 to move from the heat dissipation position to the dust removal position. When the shielding member 510 is in the dust removal position, the shielding member 510 closes the heat dissipation channel 150 and opens the dust removal channel 160. At this time, the vent 103 serves as the air inlet. Furthermore, the torsion spring 560 is used to prevent the shielding member 510 from moving from the dust removal position to the heat dissipation position. That is, the torsion spring 560 pulls the shielding member 510 along the rotation direction R2. In addition, the protruding plate portion 532 abuts against the fan housing 310 to prevent the shielding member 510 from rotating further along the rotation direction R2. In other embodiments, the electronic device may also be exempt from including the torsion spring and instead use a magnet or hook structure to prevent the shielding member from moving from the dust removal position to the heat dissipation position.

[0079] Furthermore, when the shield 510 is in the dust removal position, the fan 300 is, for example, in a closed state. A dust removal airflow F2 can be generated by any suitable means through the dust removal channel 160, thereby removing dust accumulated on the heat sink 400. For example, the dust removal airflow F2 can be generated by an airflow generating device such as a fan outside the electronic device 10, or it can be generated by the user blowing air directly onto the vent 103.

[0080] Furthermore, the shielding plate portion 511 and the connecting plate portion 512 of the shielding member 510 are not parallel to each other, for example, to guide the dust removal airflow F2 to pass more smoothly through the dust removal channel 160.

[0081] Furthermore, after being cleaned by the dust removal airflow F2, the operating temperature of the heat source (not shown) of the central processing unit (CPU) in the electronic device 10 can be reduced from 80 degrees Celsius to 74 degrees Celsius, for example, and the operating temperature of the heat source (not shown) of the graphics processing unit (GPU) in the electronic device 10 can be reduced from 76 degrees Celsius to 70 degrees Celsius, for example.

[0082] Please see Figure 7 and Figure 8 , Figure 7 and Figure 8 This is a partially enlarged view of a side sectional schematic diagram of an electronic device according to a second embodiment of the present invention. Figure 7 As shown, in this embodiment, when the shielding member 510a is in the heat dissipation position, the shielding member 510a will protrude from the housing 100. Furthermore, in the electronic device 10a of this embodiment, when the shielding member 510a is in the heat dissipation position, the magnetic plate portion 515a of the shielding member 510a will be attracted by the magnet 450a.

[0083] According to the electronic device and housing assembly disclosed in the above embodiments, since the shielding member is movably disposed on the housing and includes a heat dissipation position and a dust removal position, and can selectively close or open the dust removal channel and the heat dissipation channel, the user can clean the electronic device and housing assembly by moving the shielding member between the heat dissipation position and the dust removal position. In this way, the cost of cleaning the electronic device and housing assembly is reduced.

[0084] Furthermore, since the shielding component closes the heat dissipation channel when it is in the dust removal position, the dust removal airflow through the dust removal channel will not flow to the fan blades when dust is removed from the electronic devices and housing components. In this way, the dust removal airflow will not damage the fan blades or allow dust to flow back into the fan housing.

[0085] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the claims appended to this specification.
